Ship assistant engineers assist the ship chief engineer and the ship duty engineer in the operations of the ship’s hull. They support the operation of the main engines, steering mechanism, electrical generation and other major subsystems. They communicate with maritime engineers about the performance of technical operations. They also ensure appropriate safety and regulatory standards compliance and are able to take on higher level positions if needed.
The following job titles also refer to ship assistant engineer:
junior ship engineer
assistant shipping engineer
third assistant engineer
shipping assistant engineer
second assistant engineer
assistant ship engineer
assistant maritime engineer
maritime assistant engineer
junior chief engineer
A bachelor’s degree in marine engineering, marine technology, or a related field is generally required to work as a ship assistant engineer. These programs typically include courses in marine propulsion, marine systems, marine mechanics, marine hydraulics, marine electronics and marine engineering design.
Many marine engineers also have an associate’s or a master’s degree in marine engineering or a related field.
In some countries, a license may be required to work aboard a vessel.
ISCO skill level
ISCO skill level is defined as a function of the complexity and range of tasks and duties to be performed in an occupation. It is measured on a scale from 1 to 4, with 1 the lowest level and 4 the highest, by considering:
- the nature of the work performed in an occupation in relation to the characteristic tasks and duties
- the level of formal education required for competent performance of the tasks and duties involved and
- the amount of informal on-the-job training and/or previous experience in a related occupation required for competent performance of these tasks and duties.
Ship assistant engineer is a Skill level 3 occupation.
